ABSTRACT
BACKGROUND AND AIM: The REgistry of Selective Internal radiation therapy in AsiaNs (RESIN) was a multicenter, single-arm, prospective, observational study of 90Y resin microspheres in patients with hepatocellular carcinoma (HCC) or metastatic colorectal cancer (mCRC) from Taiwan. RESIN is the first real-life clinical study of this therapy in an Asian cohort. Study objectives were to evaluate the safety and efficacy of 90Y resin microspheres. METHODS: Adults with HCC or mCRC scheduled to receive SIRT with 90Y resin microspheres were included. Primary endpoints were best overall response rate (ORR), adverse events, and changes from baseline in liver function. Secondary efficacy endpoints included overall survival (OS). RESULTS: Of 107 enrolled patients, 83 had HCC, and 24 had mCRC. ORR was 55.41% (HCC) and 33.33% (mCRC). Of 58 HCC patients with 6-month post-SIRT data, 13.79% (n = 8) had resection, transplantation, transarterial chemoembolization, or radiofrequency ablation as the result of down-staging or down-sizing of their lesions. One hundred and ten treatment emergent adverse events (TEAEs) were reported in 51 patients, and five serious adverse events (SAEs) were reported in five patients. The most frequent TEAEs were abdominal pain, nausea and decreased appetite (HCC), and abdominal pain, decreased appetite, fatigue, and vomiting (mCRC). Two deaths due to SAEs (probably related to SIRT) were reported, both in patients with extensive HCC, active hepatitis infection, and other comorbidities. Median OS was 24.07 (HCC) and 12.66 (mCRC) months. CONCLUSIONS: Safety and efficacy outcomes with the routine use of SIRT with 90Y resin microspheres in Taiwan are consistent with published data.

BACKGROUND: Chronic hepatitis C (CHC) increases the risk of liver cirrhosis (LC) and hepatocellular carcinoma (HCC). This nationwide cohort study assessed the effectiveness of viral eradication of CHC. METHODS: The Taiwanese chronic hepatitis C cohort and Taiwan hepatitis C virus (HCV) registry are nationwide HCV registry cohorts incorporating data from 23 and 53 hospitals in Taiwan, respectively. This study included 27,577 individuals from these cohorts that were given a diagnosis of CHC and with data linked to the Taiwan National Health Insurance Research Database. Patients received either pegylated interferon and ribavirin or direct-acting antiviral agent therapy for > 4 weeks for new-onset LC and liver-related events. RESULTS: Among the 27,577 analyzed patients, 25,461 (92.3%) achieved sustained virologic response (SVR). The mean follow-up duration was 51.2 ± 48.4 months, totaling 118,567 person-years. In the multivariable Cox proportional hazard analysis, the hazard ratio (HR) for incident HCC was 1.39 (95% confidence interval [CI]: 1.00-1.95, p = 0.052) among noncirrhotic patients without SVR compared with those with SVR and 1.82 (95% CI 1.34-2.48) among cirrhotic patients without SVR. The HR for liver-related events, including HCC and decompensated LC, was 1.70 (95% CI 1.30-2.24) among cirrhotic patients without SVR. Patients with SVR had a lower 10-year cumulative incidence of new-onset HCC than those without SVR did (21.7 vs. 38.7% in patients with LC, p < 0.001; 6.0 vs. 18.4% in patients without LC, p < 0.001). CONCLUSION: HCV eradication reduced the incidence of HCC in patients with and without LC and reduced the incidence of liver-related events in patients with LC.
ABSTRACT
BACKGROUND/AIMS: Hepatitis C virus (HCV) eradication using antiviral agents augments the metabolic profile. Changes in glycated hemoglobin (HbA1c) levels in chronic hepatitis C patients who receive glecaprevir/pibrentasvir (GLE/PIB) remain elusive. METHODS: Data from 2417 patients treated with GLE/PIB from the Taiwan HCV Registry were analyzed, and pretreatment HbA1c levels were compared with 3-months after the-end-of treatment levels. A sustained virological response (SVR) was defined as undetectable HCV RNA at 12 weeks after the end of treatment. A significant change in HbA1c level was defined as the 75th percentile of the change in the HbA1c level before and after treatment (decrement >0.2%). RESULTS: Serum HbA1c levels decreased significantly (6.0 vs 5.9%, P < 0.001). Post-treatment HbA1c levels decreased in all subgroups, except in non-SVR patients (5.7 vs 5.7%, P = 0.79). Compared to patients without significant HbA1c improvement (decrement >0.2%), those with HbA1c improvement were older (60.2 vs 58.6 years, P < 0.001), had higher serum creatinine levels (1.9 vs 1.6 mg/dL, P < 0.001), triglycerides (129.8 vs 106.2 mg/dL, P < 0.001), fasting glucose (135.8 vs 104.0 mg/dL, P < 0.001), and pretreatment HbA1c (7.1 vs 5.7%, P < 0.001) and had a higher proportion of male sex (57.9% vs 50.9%, P = 0.003), diabetes (84.3 vs 16.8%, P < 0.001), more advanced stages of chronic kidney disease (CKD) (15.7 vs 11.1 %, P < 0.001), anti-diabetic medication use (47.3 vs 16.4%, P < 0.001) and fatty liver (49.6 vs 38.3 %, P < 0.001). Multivariate analysis revealed that the factors associated with significant HbA1c improvement were age (odds ratio [OR]/95% confidence intervals [CI]: 1.01/1.00-1.02, P = 0.01), HbA1c level (OR/CI: 2.83/2.48-3.24, P < 0.001) and advanced CKD stages (OR/CI: 1.16/1.05-1.28, P = 0.004). If the HbA1c variable was not considered, the factors associated with significant HbA1c improvement included alanine aminotransferase level (OR/CI, 1.002/1.000-1.004, P = 0.01), fasting glucose level (OR/CI: 1.010/1.006-1.013, P < 0.001), and diabetes (OR/CI: 3.35/2.52-4.45, P < 0.001). CONCLUSIONS: The HbA1c levels improved shortly after HCV eradication using GLE/PIB. The improvement in glycemic control can be generalized to all subpopulations, particularly in patients with a higher baseline HbA1c level or diabetes.
ABSTRACT
BACKGROUND: Metabolic Dysfunction-associated Steatotic Liver Disease (MASLD) has become a global epidemic, and air pollution has been identified as a potential risk factor. This study aims to investigate the non-linear relationship between ambient air pollution and MASLD prevalence. METHOD: In this cross-sectional study, participants undergoing health checkups were assessed for three-year average air pollution exposure. MASLD diagnosis required hepatic steatosis with at least 1 out of 5 cardiometabolic criteria. A stepwise approach combining data visualization and regression modeling was used to determine the most appropriate link function between each of the six air pollutants and MASLD. A covariate-adjusted six-pollutant model was constructed accordingly. RESULTS: A total of 131,592 participants were included, with 40.6% met the criteria of MASLD. "Threshold link function," "interaction link function," and "restricted cubic spline (RCS) link functions" best-fitted associations between MASLD and PM2.5, PM10/CO, and O3 /SO2/NO2, respectively. In the six-pollutant model, significant positive associations were observed when pollutant concentrations were over: 34.64 µg/m3 for PM2.5, 57.93 µg/m3 for PM10, 56 µg/m3 for O3, below 643.6 µg/m3 for CO, and within 33 and 48 µg/m3 for NO2. The six-pollutant model using these best-fitted link functions demonstrated superior model fitting compared to exposure-categorized model or linear link function model assuming proportionality of odds. CONCLUSION: Non-linear associations were found between air pollutants and MASLD prevalence. PM2.5, PM10, O3, CO, and NO2 exhibited positive associations with MASLD in specific concentration ranges, highlighting the need to consider non-linear relationships in assessing the impact of air pollution on MASLD.

BACKGROUND & AIMS: Diabetes mellitus (DM) is known to increase the risk of hepatocellular carcinoma (HCC) among individuals with chronic hepatitis C (CHC). We aimed to evaluate whether metformin reduces HCC risk among individuals with DM and CHC after successful antiviral therapy. METHODS: Individuals with CHC who achieved a sustained virological response (SVR) after interferon-based therapy were enrolled in a large-scale, multicenter cohort in Taiwan (T-COACH). Cases of HCC at least 1 year after SVR were identified through linkage to the catastrophic illness and cancer registry databases. RESULTS: Of 7,249 individuals with CHC enrolled in the study, 781 (10.8%) had diabetes and 647 (82.8%) were metformin users. During a median follow-up of 4.4 years, 227 patients developed new-onset HCC. The 5-year cumulative HCC incidence was 10.9% in non-metformin users and 2.6% in metformin users, compared to 3.0% in individuals without DM (adjusted hazard ratio [aHR] 2.83; 95% CI 1.57-5.08 and aHR 1.46; 95% CI 0.98-2.19, respectively). Cirrhosis was the most important factor significantly associated with higher HCC risk in Cox regression analysis, followed by DM non-metformin use, older age, male sex, and obesity; whereas hyperlipidemia with statin use was associated with a lower HCC risk. Using the two most crucial risk factors, cirrhosis and DM non-metformin use, we constructed a simple risk model that could predict HCC risk among individuals with CHC after SVR. Metformin use was shown to reduce the risk of all liver-related complications. CONCLUSIONS: Metformin use greatly reduced HCC risk after successful antiviral therapy in individuals with diabetes and CHC. A simple risk stratification model comprising cirrhosis and DM non-metformin use could predict long-term outcomes in individuals with CHC after SVR. IMPACT AND IMPLICATIONS: The current study provides evidence that metformin could reduce hepatocellular carcinoma (HCC) incidence after successful antiviral therapy among those with diabetes and chronic hepatitis C in a large-scale nationwide cohort study. Although successful antiviral therapy greatly reduces HCC risk in individuals with chronic hepatitis C, those with cirrhosis, diabetes, obesity, and the elderly remain at high risk of HCC development. We demonstrated that a simple risk model composed of two crucial unfavorable factors, cirrhosis and diabetes without metformin use, predicts the risk of HCC and major liver-related complications after successful antiviral therapy in individuals with chronic hepatitis C. Metformin use is highly recommended for individuals with diabetes and chronic hepatitis C after viral eradication to reduce the risk of HCC.

BACKGROUND & AIMS: The effect of race on routinely available noninvasive tests of fibrosis is incompletely understood. This study evaluated the performance of noninvasive tests among white and Asian patients in the STELLAR trials (NCT03053050 and NCT03053063), which evaluated selonsertib in patients with advanced (F3-F4) fibrosis due to nonalcoholic steatohepatitis (NASH). METHODS: Baseline liver biopsies were centrally read using the NASH Clinical Research Network system, and 4 noninvasive tests (Nonalcoholic fatty liver disease fibrosis score [NFS], Fibrosis-4 index [FIB-4], Enhanced Liver Fibrosis test [ELF], and liver stiffness by vibration-controlled transient elastography) were measured. The performance of these tests to discriminate advanced fibrosis was evaluated using areas under the receiver operating characteristics curves with 5-fold cross-validation repeated 100 times. RESULTS: Among 3207 patients screened with evaluable liver histology, 2281 were whites and 762 were Asians. Seventy-two percent of whites and 67% of Asians had advanced fibrosis. The areas under the receiver operating characteristics curves of the noninvasive tests for advanced fibrosis were similar in whites and Asians: 0.73 and 0.75 for NFS, 0.78 and 0.80 for FIB-4, 0.79 and 0.81 for ELF, and 0.80 and 0.83 for liver stiffness, respectively. At the published cutoffs, the tests had similar sensitivities and specificities in the 2 groups. However, the sensitivities of NFS, FIB-4, and ELF were low in both white and Asian patients younger than 40 years. CONCLUSIONS: In the global phase III STELLAR trials, the diagnostic performance of routinely available noninvasive tests for the detection of advanced fibrosis due to NASH was acceptable and similar between white and Asian patients.

Diabetes mellitus (DM) and hepatitis C virus (HCV) infection are prevalent diseases globally and emerging evidence demonstrates the bidirectional association between the two diseases. Direct-acting antivirals (DAAs) for HCV have a high treatment success rate and can significantly reduce the risks of short and long-term complications of HCV infection. However, despite the evidence of the association between diabetes and HCV and the benefits of anti-HCV treatment, previously published guidelines did not focus on the universal HCV screening for patients with diabetes and their subsequent management once confirmed as having HCV viremia. Nonetheless, screening for HCV among patients with diabetes will contribute to the eradication of HCV infection. Thus, the three major Taiwan medical associations of diabetes and liver diseases endorsed a total of 14 experts in the fields of gastroenterology, hepatology, diabetology, and epidemiology to convene and formulate a consensus statement on HCV screening and management among patients with diabetes. Based on recent studies and guidelines as well as from real-world clinical experiences, the Taiwan experts reached a consensus that provides a straightforward approach to HCV screening, treatment, and monitoring of patients with diabetes.

BACKGROUND & AIMS: A strategy to prevent hepatitis B virus (HBV) virologic reactivation (HBVr) and clinical reactivation (CR) during direct acting antiviral (DAA) treatment of hepatitis C virus (HCV)/HBV dual infection remains an unresolved issue. METHODS: Noncirrhotic patients with dual HCV/HBV infection were enrolled and allocated randomly to 1 of 3 groups as follows: 12 weeks of DAA alone (group 1), 12 weeks of DAA plus 12 weeks of entecavir (group 2), or 12 weeks of DAA plus 24 weeks of entecavir (group 3). The entire study duration was 72 weeks. The primary end point was the occurrence of HBVr (defined by an increase of HBV DNA level >10-fold with quantifiable HBV DNA at baseline or the presence of HBV DNA with prior unquantifiable HBV DNA) and CR (defined by serum alanine aminotransferase level >2-fold the upper limit of normal in addition to HBVr). RESULTS: Fifty-six patients were allocated randomly as follows: 20 patients in group 1, 16 patients in group 2, and 20 patients in group 3. In group 1, HBV DNA levels increased significantly as early as 4 weeks after initiation of DAA and persisted until the end of the study. During DAA treatment, HBVr occurred in 50% in group 1 vs 0% in group 2 and 0% in group 3 (P < .001), whereas the majority of HBVr in groups 2 and 3 occurred 12 weeks after cessation of entecavir (cumulative incidence, 93.8% in group 2 and 94.7% in group 3). Three patients (5.4%; 1 in each group) showed CR at week 48 and did not receive entecavir treatment. CONCLUSIONS: Twelve weeks of entecavir is suggested to be co-administered with DAA for HCV/HBV dually infected patients. CLINICALTRIALS: gov no: NCT04405011.

BACKGROUND & AIMS: Sofosbuvir is approved for chronic hepatitis C (CHC) patients with severe chronic kidney disease (CKD). The impact of sofosbuvir-based therapy on renal function augmentation on a real-world nationwide basis is elusive. METHODS: The 12,995 CHC patients treated with sofosbuvir-based (n = 6802) or non-sofosbuvir-based (n = 6193) regimens were retrieved from the Taiwan nationwide real-world HCV Registry Program. Serial estimated glomerular filtration rate (eGFR) levels were measured at baseline, end of treatment (EOT), and end of follow-up (EOF) (3 months after EOT). RESULTS: The eGFR decreased from baseline (91.4 mL/min/1.73 m2) to EOT (88.4 mL/min/1.73 m2; P < .001) and substantially recovered at EOF (88.8 mL/min/1.73 m2) but did not return to pretreatment levels (P < .001). Notably, a significant decrease in eGFR was observed only in patients with baseline eGFR ≥90 mL/min/1.73 m2 (from 112.9 to 106.4 mL/min/1.73 m2; P < .001). In contrast, eGFR increased progressively in patients whose baseline eGFR was <90 mL/min/1.73 m2 (from 70.0 to 71.5 mL/min/1.73 m2; P < .001), and this increase was generalized across different stages of CKD. The trend of eGFR amelioration was consistent irrespective of sofosbuvir usage. Multivariate adjusted analysis demonstrated that baseline eGFR >90 mL/min/1.73 m2 was the only factor independently associated with significant slope coefficient differences of eGFR (-1.98 mL/min/1.73 m2; 95% confidence interval, -2.24 to -1.72; P < .001). The use of sofosbuvir was not an independent factor associated with eGFR change. CONCLUSIONS: Both sofosbuvir and non-sofosbuvir-based regimens restored renal function in CHC patients with CKD, especially in those with significant renal function impairment.

BACKGROUND AND AIM: The aim of this study was to assess the impact of body mass index (BMI) on the clinical and histological characteristics of patients with nonalcoholic fatty liver disease (NAFLD). METHODS: Patients with clinically diagnosed NAFLD who received liver biopsy were retrospectively enrolled from 2007 to 2019. For comparison, all of the patients were divided into lean body mass (< 23 kg/m2 ), overweight (23-24.9 kg/m2 ), and obesity (BMI ⧠25 kg/m2 ). RESULTS: A total of 572 patients with histologically confirmed NAFLD, including 40 (6.99%) lean body mass, 54 (9.44%) overweight, and 478 (83.57%) obese patients, were recruited. Obese NAFLD patients had significantly higher grade of steatosis (grade 3: 29.92% vs 22.22% vs 12.5%, P < 0.0001) and hepatocyte ballooning (grade 2: 14.85% vs 12.96% vs 12.5%, P < 0.0001) than overweight and lean NAFLD patients. The prevalence of nonalcoholic steatohepatitis (NASH) was 22.5%, 25.93%, and 36.19% in lean, overweight, and obese NAFLD patients, respectively. Obesity was significantly associated with fibrosis severity (P = 0.03). The fibrosis index based on four factors (FIB-4) score can identify NAFLD patients without significant fibrosis or with cirrhosis. The areas under the receiver-operating characteristic curve of FIB-4 score to identify patients without significant fibrosis or with cirrhosis were 0.82 (95% confidence interval [CI]: 0.69-0.96) and 0.87 (95% CI: 0.76-0.99) in lean patients; 0.77 (95% CI: 0.61-0.93) and 0.81 (95% CI: 0.59-1.0) in overweight patients; and 0.77 (95% CI: 0.72-0.82) and 0.89 (95% CI: 0.85-0.92) in obese patients. CONCLUSIONS: The majority of NAFLD patients are obese, as defined by BMI. Obesity was significantly associated with NASH and hepatic fibrosis severity in patients with NAFLD.

BACKGROUND: Hepatitis C virus (HCV) genotype 6 mainly distributes in Southeast Asia and South China. Because of the low prevalence in developed countries, optimal treatment for HCV genotype 6 in real-world setting remains to be determined. We aimed to evaluate the effectiveness and safety of sofosbuvir/velpatasvir (SOF/VEL) and glecaprevir/pibrentasvir (GLE/PIB) for patients with HCV genotype 6 infection in Taiwan. METHODS: A total of 286 patients with chronic hepatitis C (CHC) genotype 6, 161 receiving 12-week SOF/VEL and 125 receiving 8-week GLE/PIB, were enrolled. All patients were followed up for 12 weeks after treatment completion. Demographic information, HCV viral load (VL), profiles of lipid and sugar, and adverse events were recorded and reviewed. RESULTS: Sustained virological response (SVR) rates of SOF/VEL and GLE/PIB evaluated by intention-to-treat analysis were 99.38% and 100%, respectively. SVR achieved 100%, regardless of cirrhosis or viral load (cutoff: 6 MIU/mL), of both regimens by per-protocol analysis. Skin itching was the most common adverse event, with an overall incidence of 6.64% which was more prevalent in GLE/PIB (12.0%) than SOF/VEL (2.48%). A significant decrease in the estimated glomerular filtration rate was observed in patients receiving SOF/VEL but not in those receiving GLE/PIB at the time of SVR. No patient discontinued treatment due to adverse event. CONCLUSION: The high SVR and excellent safety of SOF/VEL and GLE/PIB in real-world setting reveals that the two DAA regimens are favorable options for treatment of HCV genotype 6 in Taiwan and Asia.

BACKGROUND/PURPOSE: Direct-acting antiviral agents (DAAs) have revolutionized the paradigm for HCV treatment. However, patients with HBV and HCV co-infection receiving DAAs are at significant risk of HBV reactivation, with limited literature addressing the roles of serum chemokines/chemokines. We aimed to explore the profiles and predictive value of serum cytokines/chemokines regarding HBV reactivation in this clinical setting. METHODS: From 2017 to 2019, 25 patients with HBV and HCV co-infection scheduled for DAA therapy were prospectively enrolled. At enrolment and after DAA treatment, serial serum cytokine/chemokine levels were examined. The baseline and dynamic levels were compared between those with versus without HBV virologic (defined by an increase of serum HBV DNA to >10 times) and clinical reactivation (defined by > 1.5-fold elevated ALT level than nadir and >100 U/L; or > 2-fold increase from nadir and greater than the upper normal limit, in addition to virologic reactivation). RESULTS: There were 20 patients (80%) experiencing HBV virologic reactivation and 6 patients (24%) experiencing clinical reactivation. Patients with clinical reactivation had higher pre-treatment TNF-alpha (27.93 versus 18.85 pg/mL, P = 0.015), lower week-4 IFN-gamma (1.07 versus 8.74 pg/mL, P = 0.020) levels and significant declines of CCL2 and TNF-alpha (P < 0.05). Single or combination of these cytokines helped predict clinical reactivation (all P < 0.05). CONCLUSION: Higher serum TNF-alpha at baseline and lower IFN-gamma at week 4 were associated with mild clinical reactivation of HBV in patients with HBV/HCV co-infection receiving DAAs. Combination of these cytokines reliably predicted HBV reactivation early.

BACKGROUND/PURPOSE: The Taiwan Association for the Study of the Liver (TASL) HCV Registry (TACR) is a nationwide registry of chronic hepatitis C patients in Taiwan. This study evaluated antiviral effectiveness of ledipasvir (LDV)/sofosbuvir (SOF) in patients in the TACR. METHODS: Patients enrolled in TACR from 2017-2020 treated with LDV/SOF were eligible. The primary outcome was the proportion of patients with sustained virologic response 12 weeks after end of treatment (SVR12). RESULTS: 5644 LDV/SOF ± ribavirin-treated patients were included (mean age: 61.4 years; 54.4% female). Dominant viral genotypes were GT1 (50.8%) and GT2 (39.3%). 1529 (27.1%) patients had liver cirrhosis, including 201 (3.6%) with liver decompensation; 686 (12.2%) had chronic kidney disease. SVR12 was achieved in 98.6% of the overall population and in 98.2% and 98.7% of patients with and without cirrhosis, respectively. SVR12 rates in patients with compensated cirrhosis treated with LDV/SOF without RBV were >98%, regardless of prior treatment experience. SVR12 was 98.6%, 98.4%, 100%, 100%, and 98.7% among those with GT1, GT2, GT4, GT5, and GT6 infections, respectively. Although patient numbers were relatively small, SVR12 rates of 100% were reported in patients infected with HCV GT2, GT5, and GT6 with decompensated cirrhosis and 98% in patients with severely compromised renal function. LDV/SOF adherence ≤60% (P < 0.001) was the most important factor associated with treatment failure. Incidence of adverse events was 15.8%, with fatigue being the most common. CONCLUSION: LDV/SOF is effective and well tolerated in routine clinical practice in Taiwan. Cure rates were high across patient populations.

Programmed cell death protein-1 (PD-1) inhibitors have shown promising results for treating advanced hepatocellular carcinoma (HCC). However, the clinical utility of such inhibitors in HCC patients with vascular tumor thrombosis remains unclear. This study investigated PD-1 inhibitor efficacy in advanced HCC with macrovascular invasion in a clinical setting. Among the 110 patients with unresectable HCC treated with PD-1 inhibitors, 34 patients with vascular metastases in the portal vein and inferior vena cava were retrospectively compared with 34 patients without tumor thrombi. The vascular response and its effect on survival were assessed. Predictors of survival were identified using multivariate analysis. Among patients achieving objective response, those with and without thrombi exhibited similar response to immunotherapy and comparable survival. Among the 34 patients with tumor thrombi, including 13 receiving PD-1 inhibitors alone and 21 receiving it in combination with tyrosine kinase inhibitors, the median overall survival was 8.9 months (95% confidence interval 3.2-12.6). The objective response rate of vascular metastasis was 52.9%, and vascular responders had a significantly longer survival than did non-responders (11.1 vs 3.9 months). Failure to obtain a vascular response correlated significantly with increased post-treatment Child-Pugh score or class. Multivariate analysis showed that vascular response was a significant positive factor for longer overall survival. Treatment-related grade 3/4 adverse events occurred in 3 (8.8%) of the patients with tumor thrombi. Immunotherapy with PD-1 inhibitors may be a feasible treatment option for HCC with tumor thrombi owing to the high response rate of tumor thrombi and favorable survival outcomes.

Chronic hepatitis C virus (HCV) infection is associated with risk of cardiovascular diseases. Although direct-acting antivirals (DAA) result in rapid eradication of HCV, their long-term impact on arterial stiffness remains unclear. This study aimed to evaluate changes in parameters of central arterial stiffness from pretreatment, through sustained virological response, to one year after viral clearance. Patients with chronic HCV receiving DAA treatment were enrolled prospectively. Medical history and comorbidities of all patients were collected. Lipid profiles, liver stiffness by transient elastography and central blood pressures using pulse wave analysis of the brachial artery by cuff sphygmomanometry were measured before treatment, at viral clearance and at one year following viral clearance. Augmentation index (AIx), a parameter of aortic stiffness, was calculated as the ratio of augmentation pressure to central pulse pressure. After DAA treatment, all included patients with chronic HCV (n = 102) had achieved viral clearance. Cholesterol, low-density lipoprotein (LDL) and triglyceride/high-density lipoprotein (TG/HDL) increased significantly at viral clearance and persisted at one year (all P < .001). AIx was also elevated significantly at viral clearance and persisted one year later (P < .001). Changes in AIx remained significant only in patients with increased values from baseline in either LDL (P < .01) or TG/HDL (P < .001). Central arterial stiffness and lipid profiles in patients with chronic HCV worsen immediately after viral eradication by DAA treatment and persist at one year. Worsening of lipid profiles after DAA treatment contributes to central arterial stiffness in this patient population and persists long term.

BACKGROUND/AIMS: Direct-acting antivirals (DAAs) are highly effective in treating chronic hepatitis C virus (HCV)-infected patients. The real-world treatment outcome in Taiwanese patients on a nationwide basis is elusive. METHODS: The Taiwan HCV Registry (TACR) programme is a nationwide registry platform including 48 study sites, which is organized and supervised by the Taiwan Association for the Study of the Liver. The primary endpoint was sustained virological response (SVR12, undetectable HCV RNA 12 weeks after end-of-treatment). RESULTS: A total of 13 951 registered patients with SVR12 data available were analysed (mean age, 63.0 years; female, 55.9%; HCV genotype-1 [GT1], 57.9%; cirrhosis, 38.4%; preexisting hepatocellular carcinoma [HCC], 10.6%; and hepatitis B virus coinfection, 7.7%). The overall SVR12 rate was 98.3%, with 98.7%, 98.0%, 98.4% and 97.4% in treatment-naïve noncirrhotic, treatment-naïve cirrhotic, treatment-experienced noncirrhotic and treatment-experienced cirrhotic patients, respectively. The SVR12 rate was > 95% across all subgroups except treatment-experienced cirrhotic patients who received sofosbuvir/ribavirin (88.7%), treatment-naïve noncirrhotic patients (94.8%) and treatment-experienced cirrhotic (94.8%) patients who received daclatasvir/asunaprevir. The most important factor associated with treatment failure was DAA adherence < 60% ( adjusted odds ratio [aOR]/95% confidence interval [CI]: 117.1/52.4-261.3, P < .001), followed by GT3/GT2 (aOR/CI: 5.78/2.25-14.9, P = .0003 and aOR/CI: 1.55/1.05-2.29, P = .03, compared with GT1), active hepatocellular carcinoma (aOR/CI: 4.29/2.57-7.16, P < .001), the use of sofosbuvir/ribavirin (aOR/CI: 2.51/1.67-3.77, P < .001) and daclatasvir/asunaprevir (aOR/CI: 3.29/1.94-5.58, P < .001), decompensated liver cirrhosis (aOR/CI: 2.50/1.20-5.22, P = .02) and high HCV viral loads (aOR/CI: 2.16/1.57-2.97, P < .001). CONCLUSIONS: DAAs are highly effective in treating Taiwanese HCV patients in the real-world setting. Maintaining DAA adherence and selecting highly efficacious regimens are keys to ensure treatment success.

BACKGROUND: The detection rate of Barcelona Clinic Liver Cancer (BCLC) very-early-stage hepatocellular carcinoma (HCC) is increasing because of advances in surveillance and improved imaging technologies for high-risk populations. Surgical resection (SR) and radiofrequency ablation (RFA) are both first-line treatments for very-early-stage HCC, but the differences in clinical outcomes between patients treated with SR and RFA remain unclear. This study investigated the prognosis of SR and RFA for very-early-stage HCC patients with long-term follow-up. METHODS: This study was retrospectively collected data on the clinicopathological characteristics, overall survival (OS), and disease-free survival (DFS) of 188 very-early-stage HCC patients (≤ 2 cm single HCC). OS and DFS were analyzed using the Kaplan-Meier method and Cox regression analysis. Propensity score matching (PSM) analysis was performed. RESULTS: Of the 188 HCC patients, 103 received SR and 85 received RFA. The median follow-up time was 56 months. The SR group had significantly higher OS than the RFA group (10-year cumulative OS: 55.2% and 31.3% in the SR and RFA groups, respectively). No statistically significant difference was observed in DFS between the SR and RFA groups (10-year cumulative DFS: 45.9% and 32.6% in the SR and RFA groups, respectively). After PSM, the OS in the SR group remained significantly higher than that in the RFA group (10-year cumulative OS: 54.7% and 42.2% in the SR and RFA groups, respectively). No significant difference was observed in DFS between the SR and RFA groups (10-year cumulative DFS: 43.0% and 35.4% in the SR and RFA groups, respectively). Furthermore, in the multivariate Cox regression analysis, treatment type (hazard ratio (HR): 0.54, 95% confidence interval (CI): 0.31-0.95; P = 0.032) and total bilirubin (HR: 1.92; 95% CI: 1.09-3.41; P = 0.025) were highly associated with OS. In addition, age (HR: 2.14, 95% CI: 1.36-3.36; P = 0.001) and cirrhosis (HR: 1.79; 95% CI: 1.11-2.89; P = 0.018) were strongly associated with DFS. CONCLUSION: For patients with very-early-stage HCC, SR was associated with significantly higher OS rates than RFA. However, no significant difference was observed in DFS between the SR and RFA groups.

BACKGROUND AND AIM: It is currently unknown how hepatitis C virus (HCV) eradication with pegylated interferon and ribavirin (PR) therapy affects the incidence of new-onset liver cirrhosis (LC) in patients without cirrhosis and the incidence of decompensated liver disease (DLD) or hepatocellular carcinoma (HCC) in patients with cirrhosis. METHODS: Taiwanese chronic hepatitis C cohort (T-COACH) is a nationwide HCV registry cohort from 23 hospitals in Taiwan recruited between 2003 and 2015. This study enrolled 10 693 patients with chronic hepatitis C (CHC), linked to the Taiwan National Health Insurance Research Database, receiving PR therapy for at least 4 weeks for new-onset LC and liver-related complications (DLD or HCC). RESULTS: Of the 10 693 patients, 1372 (12.8%) patients had LC, and the mean age was 54.0 ± 11.4 years. The mean follow-up duration was 4.38 ± 2.79 years, with overall 46 798 person-years. The 10-year cumulative incidence rates of new-onset LC were 5.0% (95% confidence interval [CI]: 3.2-7.7) in patients without cirrhosis with a sustained virologic response (SVR) and 21.9% (95% CI: 13.4-32.4) in those without SVR (hazard ratio [HR]: 0.22, P < 0.001). The 10-year cumulative incidence rates of liver-related complications were 21.4% (95% CI: 11.1-37.2) in patients with cirrhosis with SVR and 47.0% (95% CI: 11.1-86.0) in those without SVR after adjustment for age, sex, and competing mortality (HR: 0.52, P < 0.001). CONCLUSIONS: Hepatitis C virus eradication with PR therapy decreased the incidence of new-onset LC in noncirrhotic patients and the incidence of liver-related complications in cirrhotic patients with CHC.

BACKGROUND AND AIM: Chronic hepatitis C virus (HCV) infection is associated with impaired renal function. The aim of this study is to explore the risk of and factors associated with end-stage renal diseases (ESRD) under maintenance dialysis among HCV patients after anti-HCV therapy. METHODS: A total of 12 696 HCV-infected patients with interferon-based therapy, including 9679 (76.2%) achieving sustained virological response (SVR), were enrolled from 23 hospitals in Taiwan. RESULTS: During a mean follow-up period of 5.3 years (67 554 person-years), the annual incidence of 4.1/10 000 person-years, 4.0/10 000 and 4.7/10 000 person-years among SVR patients and non-SVR patients, respectively. History of diabetes and baseline estimated glomerular filtration rate < 60 mL/min/m2 , instead of SVR, were the significant risk factors for developing ESRD with maintenance dialysis after anti-HCV therapy (adjusted hazard ratio 7.75 and 9.78). CONCLUSION: Diabetes and baseline impaired renal function were strongly associated with progression to ESRD with maintenance dialysis among chronic HCV-infected patients after antiviral therapy.

BACKGROUND/PURPOSE: Genotype 2 (GT2) hepatitis C virus infection is the second common genotype in Taiwan. Real-world experience of ledipasvir/sofosbuvir (LDV/SOF) for GT2 infection is limited. The aim of this study is to evaluate the effectiveness and safety of LDV/SOF in patients with GT2 chronic hepatitis C (CHC) infection. METHODS: CHC patients with GT2 infection receiving 12 weeks LDV/SOF from three hospitals were enrolled. HCV RNA was checked at baseline, end-of-treatment and 12 weeks after completing treatment. Demographic data, adverse events, renal function and metabolic profiles were recorded. RESULTS: Among 392 enrolled patients, 33 patients (8.4%) were cirrhotic. Sustained virological response (SVR) rate was 96.7% (379/392) by intention-to-treat analysis and 97.2% (379/390) by per-protocol analysis. The SVR rate was lower in cirrhotic patients than in non-cirrhotic patients (90.6% vs 97.8%, p = 0.053). Two cirrhotic patients who took LDV/SOF plus ribavirin both achieved SVR. Neither drug-related severe adverse events nor discontinuation due to drug-related adverse event were reported. The estimated glomerular filtration rate (eGFR) remained stable in patients with chronic kidney disease 3a/3b. CONCLUSION: Twelve weeks of LDV/SOF treatment provided an excellent and safe regimen for GT2 CHC infection, particularly in non-cirrhotic patients.
